  • Scully, Sean (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-05-31)
    The protein and amino acid metabolism of thermophilic bacteria has been a neglected aspect of their physiology despite its biotechnological potential. Under anaerobic conditions, the metabolism of many proteogenic amino acids requires the presence of ...
  • Ingvadóttir, Eva María; Scully, Sean; Orlygsson, Johann (Elsevier, 2018-08-30)
    The dataset details the fermentation of D-glucose, L-rhamnose, and L-fucose and their end-product formation by the moderate thermo-phile Clostridiumstrain AK1 (DSM 18778) as related to the work described in “Propanediol from L-rhamnose using the ...
  • Scully, Sean; Orlygsson, Johann (Elsevier BV, 2019-06)
    The dataset describes the catabolism of the 20 proteogenics amino acids and their end products by Thermoanaerobacter strain AK85 under different electron scavenging conditions with an emphasis on the branched-chain amino acids as reported in Scully and ...
  • Silva, Teresa Sofia Giesta da (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2018-12-14)
    Krill are an important component of the Icelandic marine ecosystem. Given their important ecological niche, as conveyors of biological production between phytoplankton and higher trophic levels, fluctuations in krill abundance can have large impacts ...
  • Guðbrandsson, Jóhannes (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-04-26)
    The four morphs of Arctic charr (Salvelinus alpinus) in Lake Þingvallavatn, Iceland, which differ in many phenotypic traits related to morphology, life history, and feeding ecology, are believed to have evolved locally within the lake after the retreat ...
  • Knobloch, Stephen (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-05)
    Sponges (phylum Porifera) are considered one of the oldest extant lineages of the animal kingdom. Their close association with microorganism makes them suitable for studying early animal-microbe symbiosis and expanding our understanding of host-microbe ...
  • Beck, Samantha V. (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-01-30)
    Intraspecific variation in egg size and its effects on offspring fitness is well documented in fishes. Yet whether or not differential per propagule maternal investment (egg size) can influence phenotypic diversification is little understood. Arctic ...
  • Kreiling, Agnes-Katharina (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-10)
    Freshwater springs are thermally stable environments which are largely unaffected by changes in air temperature. They could thus have the potential to buffer rising temperatures and serve as small-scale refugia for aquatic invertebrates in a warming ...
  • Gudmundsdottir, Ragnhildur (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-10)
    Crangonyx islandicus is a groundwater amphipod endemic to Iceland. Genetic analysis suggests that the species has been diverging in Iceland for at least 4.8 Myrs indicating it has survived in a subglacial refugia as Iceland was repeatedly covered by ...
  • Magnúsdóttir, Hildur (Háskóli Íslands, 2020-10)
    Variation in morphology of shelled marine gastropods across small spatial scales may reflect restricted population connectivity, resulting in evolutionary or plastic responses to environmental heterogeneity. Species delimitation of shelled gastropods ...
  • Robertson, Peter A.; Mill, Aileen; Novoa, Ana; Jeschke, Jonathan M.; Essl, Franz; Gallardo, Belinda; Geist, Juergen; Jarić, Ivan; Lambin, Xavier; Musseau, Camille; Pergl, Jan; Pyšek, Petr; Rabitsch, Wolfgang; von Schmalensee, Menja; Shirley, Mark; Strayer, David L.; Stefánsson, Róbert A.; Smith, Kevin; Booy, Olaf (Springer Science and Business Media LLC, 2020-06-30)
    Managing the impacts of invasive alien species (IAS) is a great societal challenge. A wide variety of terms have been used to describe the management of invasive alien species and the sequence in which they might be applied. This variety and lack of ...
  • Macdonald, Jed (University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-05)
    Movements of animals en masse are impressive phenomena that continue to fascinate scientists of all persuasions. Fishes display some of the most striking examples, and an extensive literature has explored the subject in marine species with long ...
